Conclusion on classification
Based on a 48-hour EC50 in daphnia of 0.96 mg/L and a 72-hour EC50 in algae of 0.23 mg/L, and the fact that the test substance is not readily biodegradable, the test substance should be classified as R50/53 (Very toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment) according to EU Directive 67/548/EEC and Acute Env. Tox. Category 1 (H400: Very toxic to aquatic life) and Chronic Env. Tox. Category 1 (H410: Very toxic to aquatic life with long lasting effects) according to EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008.
In accordance with article 10 of the CLP Regulation (EC) No 1272/2008, if an M-factor is not yet given in Part 3 of Annex VI to the CLP Regulation, an M-factor should be determined and a scientific justification provided, when classifying substances for Acute Category 1 or Chronic Category 1. For this substance, adequate acute aquatic data are available in aquatic invertebrate and algae. An Acute M-Factor is based on the lowest reported effects in the most sensitive species aquatic invertebrate. Therefore the M factor is 1 based on the 48-hr EC/LC50 of 0.96 mg/L in aquatic invertebrate and the 72-hr EC/LC50 of 0.23 mg/L in algae.
In accordance with article 10 of the CLP Regulation (EC) No 1272/2008, if an M-factor is not yet given in Part 3 of Annex VI to the CLP Regulation, an M-factor should be determined and a scientific justification provided, when classifying substances for Acute Category 1 or Chronic Category 1. No chronic data were available in fish, invertebrates, and algae; however acute data were available in invertebrates, and algae. The test substance is not readily biodegradable. Therefore M-Factor is based on the lowest reported acute effects in the most sensitive species, invertebrate and algae. The M factor is 1 based on the 48-hr EC/LC50 of 0.96 mg/L in aquatic invertebrate and the 72-hr EC/LC50 of 0.23 mg/L in algae.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
